DESCRIPTION
The TC3947 is a self-bias Cu-based ceramic packaged device with TC1401N PHEMT GaAs FETs, which is designed
to provide the single power supply application. The Cu-based ceramic package provides excellent thermal
conductivity for the GaAs FET. The devices only need to provide the positive voltage to drain and ground the source,
which is suitable for oscillator, power amplifier application in a wide range of commercial application. All devices are
100% DC tested to assure consistent quality.
